HYDBOCARBON-BUBNER.

To aZZ'wz/m t may concern:

Be it known that I, GARNET W. CoEN, a

citizen of the United States, residing at Venice, in the county of LosAngeles and State of California, have invented new and usefulImprovements in Hydrocarbon-Burners, of'which the following is'aspecification.

VThis invention relates to improvements in hydrocarbon burners, and itis an object of the invention` to rovide a v-n'ozzleportion having;tangential? arrangedV Aopenings for admitting the hy rocarbon productsto a circular chamber adjacent t'o a' discharge out- Intheaccompanyingdrawing forming a part of this specification, Figure 1 is a 1ongitudinal'section' of the improved burner,

Fig. 2" is an enlarged transverse sectional viewtaken upon the line 2-.2of Fig. l1. Fig. 3 is a detail perspective View of the adjustable nozzlecontrollingmember. y

The details 'and' featuresl ofthe invention 4 will nowbe moredparticularly described, reference being ha tothe said drawing "in which'10 indicates a supply pi 11 acasing and 12 a discharge pipe.v e casing11 may be of any ordinary or desired construction, having threadedconnections from the .outlet pipe 12 valve vstem gland and the inlet p1e 10.

- e discharge pipe 12 is threaded at its I .outer end and adapted toreceive an interthe cap 14 is located a nozzle 16 havingan nallythreaded cap 14 having an overhanging inwardly extending annular lape 15for holding anozzle'in position. ithin annular flan e 17 formed upon theouter end thereof whic is adapted to fit between the flange 15 of the caand the end of the pipe 12. By screwing t e cap 14 tightly in place uponsaid ange 17 the nozzle is centrally held in place within the bore ofthe dischar e 1pc 12 as clearly shown in Fig. 1. The o y portion of thenozzle is of a suciently smaller diameter than the bore of theSpecication of Letters Patent. application mea rerruary 5, 191e. serialno. 375,662. o

about the said body portion, for the hydro`V carbon productsto beburned. 'lhe nozzle 16 is also centrally bored and the inner end' of thebore is tapered as shown at 18 so as to tend to convergev and direct thehydrocarbon materials toward the small discharge outlet 419. The/wallsof the nozzle are also formed with" inlet passages 2O extending fromjust inside the flange 17 inwardly. To secure the desired resultv in theatomizing anddischarging of the hydrocarbon products the inlet passages20 are arranged tangentially with respect to the bore of the nozz'le 16-so'that the'mat'erials forced into the nozzle through said passageswill'be given' a whirling tangential direction within' the same and'will be so concentrated upon the tapered end surface of the 'bore and atthc discharge opening 19 -thatra diverging s ralaly t e the end of theburner. The structure will result in a close cone shaped\flame inburning the fuel.

dit

In using the device the hydrocarbon ma- 'terials are usually deliveredjin the pipe 10 :to the burner under .pressure and preferably also in apreheated condition, the orclng of the materials, thus further tendingto impart a high velocity to the materials passing through the passages20 to the outlet .chamberthusproducing a thorough twisting or whirlingof the hydrocarbon products, which, upon being released through theoutlet 19, will be thoroughly disintegrated by centrifugal force andenter the furnace in a completely atomized condition.

The inlet apertures or passa es of the burner may be enlarged ordimlnished in size. `In the device shown the passages-20 are in the formof tangentially arranged slots. Movably mounted within the nozzle 16 isan adjustable member 26 having a cylindrical body portion formed withtangential rojections 27 adapted to extend into the s ots 20. so as tolill the same. The said member 26 is arranged to reciprocate within thebore of the nozzle, the projections 27 being also reciprocated therebyin the slots 20 for increasing or diminishin their o enin The saidmember 26 is a so provided with a pin projection 28 adapted to passthrough the discharge openin Y19 wli'en it The said member 26 is alsoprovi ed with a ar e orifice.

screw threaded bore adapted to engage the threaded end 30 of-a valvestem 31. The other end of the valve stem projects through a'packing.land 32 in the easing 11 and is provided withl la handle 13 by which itmay be turned. By turning said stem the member 26 may be moved back andforth in adjusting the size of the passages to vary t the action 'of theburner. By controlling the area of said passages 20, the maintenance ofthe' maximum velocity in the hydrocarbon material passing through thesaid passages y 20 under varying initial pressures in the burner up tosaid passages is obtained and the flow of the hydrocarbon' material tothe nozzle chamber,v may beabsolutely controlled at this point withoutdecreasingits velocity through said passa-ges. Thus ifthe flow to theburner is decreased by an suitable means (not shown) the pressure 1nlthe discharge pipe 12 would be decreased, resulting in a decreasedvelocity of the hydrocarbon forced through passages 20, therebyreducingthe rotat1ons ofthe material in the noz? What- I claim is:-.. y

1. A hydrocarbon burner'having a nozzle formed with a central chamberand an outlet passage, the walls vof said chamber having tangentialslots for: admitting hydrocarbon products. within the nozzle chamber, amember monntedin said nozzle and ided by said slots and adapted to partay or entirely closethe said slots, and means for operating saidmember-.A

2. A hydrocarbon burner'having a nozzle formed with a central chamberand an outlet passage, the walls of said chamber havingslots extendingfrom said outlet passage to its inner rim, a valve memberto lit saldchamber and provided with guides to'- engage and'register in said slots,and means to actuate the valve member. Y

3. A hydrocarbon burner having a nozzle formed with a central chamberand outlet passage, the walls of said chamber having slots extendingfrom the outlet passage to its inner rim, a `valve Vmember to fit saidchamber, a cylindrical needle point adapted to clean said outletpassage, and a screw thread in said valve member adapted to engage athreaded valve stem to actuate the same.

` In witness that I claim the foregoing I have hereunto subscribed myname this 25th day of January, 1912.
